Currently when the following option below is enabled the Public portal is in a default state without any customizations however in it's default state there is a link for Bomgar. We would like to have this setting enabled but not have a link to Bomgar. So if this settings is enabled there should be some more options to somewhat customize links.
Enabling this causes the Public Site to send the Content-Security-Policy HTTP header with a value of default-src 'self'. This header asks browsers not to allow your Public Site to load resources - e.g. images, scripts, stylesheets, fonts - from any other websites, to prevent inline scripts from running, and to ignore inline CSS styles. You should not enable this if you have customized your Public Site template to use external resources, inline scripts, or inline styles. This setting requires the "Force Public Site to Use HTTPS" setting to be turned on above.
